1'! Claims.

This invention relates to improvements in attachments adapted to be used in connection with typewriters for supporting and feeding to the typewriter a plurality of strips or paper with interleaved carbon sheets therebetween.

It is an object of this invention to provide, in connection with a typewriter attachment, means for supporting the leading ends of strips of paper as they are written on, said means being also 0 adapted to be used for supporting auxiliary and additional sheets of paper to be written upon and carbon sheets associated therewith.

It is also an object of this invention to provide a typewriter attachment which cooperates with the typewriter in feeding strips of paper to the typewriter according to the following method: J.) Thestrips are arranged in a writing position with the carbon sheets interleaved there between and the pins are mounted in the holes;

(2) the strips and sheets are advanced during the process ofwriting and billing with the front pins in the holes; (3) after the billing and writing have been finished the pressure rolls are released I from the platen and the sheets-removed from the front pins; (4) immediately after such release the strips and interleaved carbon she'etsare carried back by hand and spring action until the carbon sheets'reach a point where they are released from the pressure rolls and the platen;

during this period you hold the rear pins out of ,the paper sheets; (5) the pressure rolls are again caused to cooperate with the platen to grip the strips of paper with the ends of the carbon sheets behind the platen; (6) the strips of paper are advanced independently of the carbon sheets by the rotation of the platen until the third crease from the leading ends of the stripsof paper comes opposite the pointer; (7) the strips of paper with the carbon sheets interleaved therebetween are advanced until the first line of perforations shows in front of the typewriter platen; (8) the writtenon bills and the strips of paper are then torn off.

These and other advantages will appear from the following description taken in connection with the drawings' Referring to the drawings:

Figure 12 is a diagrammatic view showing in side elevation the mechanism of Figure 11.

The present attachment is adapted to be used in connection with a typewriter l which has the usual platen 2 and lever 3 for releasing the platen- 3o engaging rolls. For the purpose of supporting the attachment, the typewriter has therein a bracket 4 provided with upstanding arms 5. Each arm has therein a clip 6 to receive a leg I attached to the lower end of the-attachment frame by means of rivets and spacers 8. These legs are attached to sides 9 of the frame. These sides are connected at their lower ends by a lower bar [0 and at their upper ends by an upper bar H which is in front of the upper ends of. the

sides. The sides are also braced. by diagonally extending braces l2. On the lower bar. I 0 are two brackets l3 which rotatably support the ends of the shaft 14. This shaft is provided adjacent each end with a sprocket l5. At the other end of the 45 frame remote from the bar' l0 there is a shaft l6- journaled at each end in one of the sides. On this shaft are sprockets I I connected with the sprockets l5 by means of chains l8. Between the sprockets Ii there is rotatably mounted on the shaft l6 a roller or drum lfla used for supporting the strips'of paper and holding them out of contact with'the sprocket as they pass over the rollthis housing is attached one end of a coil spring 20 which has. its other end attachedto the shaft lli. Thisspring is brought under tension during the forward feeding of the strips of paper and then the strips of paper are released, tend to reverse their travel.

Immediately, above the shaft l6 and supported by the ends of the sides is a shaft 2| rotatably mounted in the ends and has thereon a pair of spaced guide discs 22 for engaging the edges of the superimposed strips of paper to properly guide them as they pass over the upper end of the frame and down to the typewriter. The sides of the frame are U-shaped with the arms thereof projecting toward the interior of the frame. On the rear of the frame is a rear plate 23, which is attached to the chains in any suitable manner, so that whenever the chains travel the rear plate moves with them. This plate engages at each end with the faces of the rear arms of the sides.

and is provided with fingers 24 for engaging the front of the rear arms for holding the plate againstthe sides.

The upper end of the rear plate, at each end thereof, has a struck-up portion 25 which forms a bracket for supporting in a fixed position one end of a rod 26 which extends from one side of the frame to the other and serves to hold in proper position the strips of paper as they pass up the back of the frame. This rod has at each end adjacent the part 25, a guide disc 21 adapted to engage adjacent edges of the strips of paper. These discs are adjustable by means of screws 28.

On the lower edge of each end of the back plate is a bracket 29. At the inner end of each bracket j is an arm 30. These arms rotatably support .a

roller or rod 3 I. On the outer end of each brack- -et 29 is an arm 32 to which is pivoted one end of a lever 33 by means of a pivot pin or bolt 34.

These levers 33 are connected intermediate their ends by means of a back bar 35, to which one end of a coil spring 36 is attached, while the other end of the coil spring is attached to the rod 26. This spring tends to hold the back bar in engagement with the strips of paper.

Extending forwardly from the back bar are two pins 31 adapted to pass through holes providedtherefor in the strips of paper for aligning the strips of paper and advancing the strips of paper when the chains and sprockets are caused to operate.

Slidably mounted'on the front of the frame and in engagement with the front arms of the sides is a carbon carrier plate 38, which is also attached to the chain in any suitable manner so that whenever the chain moves this carbon carrier plate is caused to travel one way or the other. This carbon carrier plate engages the front surface of'the sides and has at each end a tongue 39 to engage the rear of the front arms for the purpose of holding the carrier in cooperation with the side members forming the frame.

At each end of the carbon carrier, and projecting downwardly therefrom, is a bracket 40 which has extending forwardly therefrom a pin which has notches 42 intermediate its ends-and at its forward end has an upwardly extending pin 43.

These notches are adapted to receive the slotted ends of a spring plate 44 used for the purpose of holdingthe carbon sheets upon the pins. The upwardly projecting pins 43 serve to prevent the carbon sheets from becoming dislodged from the pins 4| in the event that theplate 44 is not used.

Each side member is provided adjacent its upper end with a stop '45 to limit the upward movemeans of an arm 48.

ment of the carbon carrier during the backward movement of the stripsof paper and the carbon sheets.

The upper bar I I is held in spaced relation to I the upper ends of the sides by means of spacer blocks 46. These blocks cause the upper bar to extend forward from the upper end of the sides and frame. To the central part of the upper bar there is attached a channel member 41 by On top of the upper bar, and immediately above the channel member 41, are two spaced standards 49 connected together by means of a common footmember 50 attached to the upper bar by means of screws 5|. These screws also pass through the arms 48 and serve v to hold the channel member in a rigid position with relation to the upper bar.

Extending through the standards intermediate their ends is a\shaft 52 which supports between the standards a drum 53 rigidly attached thereto. 0 On one of the standards, fitting over one end of the shaft 52, is a'spring housing 54 to which one end of a coil spring 55 is attached, while the other endof this coil spring is attached to one end of the shaft 52.

The channel member 41 has slidingly mounted therein a channel-shaped slide member 56 which has in its lower end a plug 51, provided with a notch 58. In this plug extending .across the notch 58 is a pin 59 to which one end of a tape 60 is attached, while the other end of this tape is attached to the drum 53. The lower end of the slide member is provided with a cross bar 6| attached at its medial point by means of screws 62 to the lower end of the slide member. These screws not only serve to hold the cross bar on the l face with a stop. 64 adapted to engage the lower end of the channel member 41' for limiting the upward movement of the slide member. This stop may be adjusted with relation to the slide member. One of the side members 9 is provided with a pointer 65, as shown in Figs. 2, 3 and 9.

The strips of paper tobe fed through the typewriter through the instrumentality of the attachment are indicated by the numeral 66, while the pile from which the superimposed strips of paper are fed is indicated by the numeral 61. These 65 strips are divided by cross-perforations into superimposed aligned tickets or bill forms. These tickets or bill forms have adjacent their lead-- ing ends holes 69 adapted to receive first the pins 31 located on the back bar 35, and thereafter the 60 pins 63 located'on the cross-bar at the lower'end of the slide member 56. l 3

The slide member 56, the cross-bar 6| and the pins 63 thereon are adapted to be used for supporting in connection with the strips of paper and carbon sheets, additional and extra sheets of paper and carbon sheets in the manner shown in Figs. Hand 12. In these Figures'll and 12 the extra sheets of paper are indicated by the 70 numeral 10, while the extra carbon sheets are indicated by the numeral ll. These extra carbon sheets are not supported by the carbon carriers andare in no wise connected thereto physically. The extra sheets of paper are not operatively connected to any part of the typewriter attachment except the pins.

Figure 1 shows the position of the various parts at the beginning of any writing operatiom Figure 5 illustrates the position of the carbon sheets and strips of paper with relation to the apparatus at the end of any writing period.

From the time the strips and interleaved carbon sheets are in the position shown in Figure 1 until they are in the next successive similar position, the following operations take place:

(1) The arrangement shown in Figure 1 is the first step in the operation, which is the positioning operation; I

(2) The second step is the advancement ofthe strips of paper and carbon sheets for billing and writing purposes. During this operation the strips of paper and sheets of carbon advance to' the position shown in Figure 5.

(3) The next operation consists in releasing the pressure rolls from the platen of the typewriter, whereby the strips of paper and carbon sheets are released and may freely move independently of the platen.

(4) The strips of paper and interleaved carbon sheets are moved backwardly by hand in cooperation with the various springs until the advanced ends of the carbon sheets pass beyond the platen, so that the advanced ends of the strips of paper may be gripped between the pressure rolls and the platen without gripping the carbon sheets.

(5) The pressure rolls are again brought into engagement with theplaten, thereby re-gripping the strips of paper so that a further rotation of the platen will advance the strips of paper without advancing the carbon sheets since the carbon sheets are free from the platen.

(6) The back bar has been moved backwardly,

bringing the pins out of the holes in the strips of paper, thereby permitting the advancing of the strips of paper without the movement of the chains and sprockets.

(7) After the pins are released from the strips of paper, the strips of paper are caused to be advanced by the rotation of the platen until the secondcreases from the leading ends of the strips come to a position opposite the pointer 65. At

this point in the operation the holes in the strips paper the platen is further operated toadvance" the strips of paper and the carbon sheets therebetween.

(10) The bills written upon are then torn off;

and

(11) The strips and carbon sheets interleaved therebetween are advanced for writing purposes to the position shown in Figure 1.

This, series of steps forms a complete-billing and advancing operation, and such steps are repeated with each successive billing operation.

By my invention I am enabled to secure the advantage of aligning and supporting the free ends of the sheets while they are being written upon, and 'of preventing them from falling over in front of the operator on the machine. They are yieldingly guided upwardly in aligned condition. I am enabled to have the further advantage of being able to add-supplementary sheets between the ends of the main sheets that are being written upon, and their associated carbon sheets,

when such extra supplementary sheets are necessary.

It will be understood that I desire to comprehend within my invention such modifications as come within the scope of my claim and my in- 5 vention.
